Table 27. Radio Settings screen settings (continued)

Setting	Descriptions
Mode	Specify the wireless mode in the 2.4-GHz band by making a selection from the
	drop-down list:
	• g and b. In addition to 802.11b- and 802.11g-compliant devices,
	802.11n-compliant devices can connect to the wireless access point because
	they are backward compatible.
	• g only. 802.11g- and 802.11n-compliant devices can connect to the wireless
	access point, but 802.11n-compliant devices function below their capacity in
	802.11g mode. 802.11b-compliant devices cannot connect.
	• ng. This is the default setting for most countries. 802.11g- and
	802.11n-compliant devices can connect to the wireless access point.
	802.11b-compliant devices cannot connect.
	• n only. Only 802.11n-compliant devices can connect to the wireless access
	point.
	Note: If your network uses 802.11n devices only, configure WPA2 to enable the
	802.11n devices to function at full speed.
Channel Spacing	For the ng and n only modes, specify the channel spacing by making a selection
	from the drop-down list:
	• 20/40MHz. Select this option to improve the performance. Some legacy
	devices (that is, devices that function only in b or g mode) can operate only in
	20 MHz.
	• 20MHz. Select this option if your network includes legacy devices. This is the
	default setting.
	Note: The channel spacing is fixed at 20 MHz for the g and b and g only modes.
Current Channel	This is a nonconfigurable field that shows the current channel if you have
	selected Auto from the Channel drop-down list.
Channel	Specify the channel you wish to use on your wireless LAN by making a selection
	from the drop-down list. The wireless channels and frequencies depend on the
	country and wireless mode. The default setting is Auto.
	Note: It should not be necessary to change the wireless channel unless you
	notice interference in the network (indicated by lost connections or slow data
	transfers). If this happens, you might want to experiment with different channels
	to see which is the best. For more information, see Operating Frequency
	(Channel) Guidelines following this table.
	Note: For more information about available channels and frequencies, see
	Physical and Technical Specifications on page 396.
